Abstract

The invention, which relates to the technical field of the X ray, discloses a thin-film photocathode distributed X ray generating device comprising a driving light source array including a plurality of driving light sources arranged in an array, a thin-film photocathode, an anode target, a vacuum container, and a control system. The multiple driving light sources of the driving light source array emit lights according to a predetermined sequence and focus positions on the anode target change based on the predetermined sequence, so that different positions on the anode target emit X rays. According to the X ray generating device provided by the invention, X rays at multiple viewing angles can be generated without mechanical movement, thereby improving the checking efficiency; and the reliability and stability are high. In addition, the invention also discloses a CT device including the thin-film photocathode distributed X ray generating device.

Description

technical field [0001] The invention relates to the technical field of X-rays, in particular to a thin-film photocathode distributed X-ray generator and CT equipment including the thin-film photocathode distributed X-ray generator. Background technique [0002] X-rays are widely used in industrial non-destructive testing, safety inspection, medical diagnosis and treatment and other fields. In particular, X-ray fluoroscopy imaging equipment made by utilizing the high penetrating ability of X-rays plays an important role in every aspect of people's daily life. The early days of this type of equipment were film-type plane perspective imaging equipment. The current advanced technology is digital, multi-view and high-resolution stereoscopic imaging equipment, such as CT (computed tomography), which can obtain high-definition three-dimensional graphics or slices Graphics, are advanced high-end applications. [0003] In the existing CT equipment, the X-ray generating device needs...
